specimen is distinctly proccelous, like some of the lumbars 

 of /. prestwichi ; it is figured by Owen in his i Wealden 

 and Purbeck Eeptilia,' snppl. ii. pi. ix., as Cetiosaurus 

 brevis, and erroneously stated to be the specimen from 

 Culver Cliff noticed by him in the ' Eep. Brit. Assoc' for 

 1841, p. 94, under that name. 



Mantell Collection. Purchased, 1853. 



28508. A posterior dorsal or lumbar vertebra, wanting the greater 

 portion of the neural spine ; probably from the Isle of 

 Wight. Dixon Collection. 



28635. A somewhat larger posterior dorsal or lumbar vertebra, 

 {Fig.) wanting the summit of the neural spine ; from Brook. 

 This and other vertebrae from the same locality appear to 

 have been associated with the coracoid No. 28643 ; they 

 were referred in MS. by Mantell to Pelorosaurus, an iden- 

 tification which, although apparently subsequently aban- 

 doned by him, was followed to a certain extent by Owen. 

 The present specimen is figured by the latter writer in his 

 ' Weald en and Purbeck Eeptilia,' suppl. ii. pi. viii., as 

 Cetiosaurus, while on p. 37 of the same work it is referred 

 to Pelorosaurus, without any reference to its being the 

 specimen figured under the former name. In general 

 contour this specimen presents a striking resemblance to 

 the lumbar vertebra of /. prestwichi figured by Hulke in 

 the ' Quart. Journ. Geo!. Soc' vol. xxxvi. pi. xix. figs. 6-8.
